FIELD OF THE INVENTION

The present invention is related to bubble-making for such reasons asentertainment and visual effect. The invention is also related tothrow-able spinning toys such as flying disks. More specifically, thisinvention is related to methods and systems for making bubbles fromthrowable spinning toys, employing the forces created by the spinning todeliver a stored bubble-making solution to the air through which the toyis thrown.

BACKGROUND AND OBJECTS OF THE INVENTION

There are devices in the prior art for producing bubbles from thrownspinning toys. But to date, all of these have been dysfunctional . . .at least to a degree sufficient to prevent them from having success inthe marketplace. They have suffered from such ill effects as excessivecomplexity causing unreliability or high cost, unreliable delivery ofbubble-making solution to the airstream, inadvertent leaking of thebubble-making solution while the device is in use, and inadvertentleaking of the solution when the device lands and rests in anyorientation other than right side up. The leaking of solution over thesurface of the disk limited these devices to use as throw-only devices,because catching a slippery flying disk is difficult and unpleasant.

A bubble-making flying disk is described in U.S. Pat. No. 5,393,256(Mitchell) that contains and converts bubble solution as it spins alonga flight path. This device was in fact commercialized exactly as taughtin the patent, but was unsuccessful due to inadvertent leaking of itsbubble-making solution during common use. While one of Mitchell's statedgoals was to minimize such inadvertent leaking, he relied on a “partialvacuum effect” to accomplish this, which effect was not functional incertain common landing positions, allowing his bubble-making solution toleak profusely during those positions.

Mitchell proposed that even when his flying disk landed upside-down, thepartial vacuum effect would retain the fluid within his reservoir. Andthat effect did serve this function when his flying disk landedupside-down, so long is it landed in a level or near-level upside-downposition. However, flying disks thrown in real-life situations rarelyland in a level or near-level position. They most often land in tiltedpositions to some degree, and Mitchell's partial vacuum effect wasineffective in such upside-down and tilted positions.

Mitchell's device admittedly cannot prevent leakage from his feed holes22 during upside-down but even slightly tilted positions. Referring toCol 6 lines 23-33, Mitchell explains how his “vacuum effect” acts to“substantially” retain the fluid within reservoir 20 when the toy isupside down and his holes 22 are positioned below the bubble solution'ssurface level. Mitchell describes the fluid retention as “substantial”(not completely) because it is obvious that such a “vacuum effect” canonly exist when all of holes 22 are below the bubble solution's surfacelevel. Whenever his toy lands upside down in less than a perfectlyhorizontal disposition, as would be very common, such that one of moreof his holes are below and one or more are above the bubble solution'ssurface level, those holes above the surface level will form vents toallow inflow of air and thereby cancel the vacuum within his reservoirand thereby allow leakage from those holes below the surface level.Indeed, Mitchell expressly admits that the fluid will leak from the feedholes 22 of reservoir 20 in the absence of a partial vacuum situation(Col 7 lines 7-11), and explains that an overflow chamber 50 may beadded to capture fluid that leaks from reservoir 20 through holes 22during those situations. In all embodiments of the Mitchell devicebubble solution travels on the lower surface of the disk (Col 5 lines37-40), “This enables the solution to travel from the reservoir 20directly onto the lower surface 16 in an uncontained, uncoveredcondition” (Col 8 lines 18-19) “conveying said bubble solution acrossthe lower surface”. Therefore the bottom surface of the Mitchell deviceis admittedly covered with a film of bubble solution, which is preciselywhere users grip and handle flying disks while playing catch with them.Because such common situations did admittedly allow leakage, and in allcases the device is covered with a film of sticky bubble solution,Mitchell was dysfunctional at least to the degree that his device wasnot marketable and his commercialized product was unsuccessful andshort-lived for these very reasons, leaving an as-yet unfulfilled needin the marketplace.

“Hydrostatic valving” is a known phenomenon related to water withintubes wherein capillary forces and water surface tension may be employedto operate as flow/no-flow valving for the water by balancing the tubelength and diameter to allow flow through the tube only upon theapplication of a predetermined linear force vector within the tube.Capillary forces cause water and other liquids of low viscosity toadhere to the inner wall of small-diameter tubing, either drawing thewater into the tubing or acting to retain the water in the tubingagainst removal forces. Articles and papers such as Cohesion andAdhesion in Liquids: Surface Tension and Capillary Action, by OpenstaxCollege, Fluidics—The Link Between Micro and Nano Sciences andTechnologies, by Chih-Ming Ho, A Review of Microvalves, by Kwang W Ohand Chong H Ahn, Centrifugal microfluidics for biomedical applications,by Robert Gorkin et al, attest to the knowledge in the public domainrelated to this phenomenon for use as componentless valving with water.However, the effects of fluid viscosity and surfactance wereunappreciated as related to hydrostatic valving using highviscosity/high surfactance fluids, so hydrostatic valving wasunobtainable with such fluids as bubble-making solution.

Research has determined that flying disks typically spin in flight ataround 6 RPS. Flying disks are generally of two common outer diameters;10 inches and 11 inches. The outer edge of the disk will typically bespinning around the disk's axis during flight at between 1884 and 2007inches per minute.

It is an object and benefit of the invention to provide a bubble makingsystem which provides the benefits of but eliminates the flaws andlimitations of prior art such as Mitchell. More specifically, it is aprimary object of the invention to provide such a system which does notinadvertently leak during any commonly expected use or condition andstays dry in all surface areas utilized by users, and which accomplishesthese objectives with a minimum of complexity and components. It is afurther object and benefit of the invention to obtain this benefitthrough the use of phenomena akin to hydrostatic valving to optimizereliability, decrease complexity, and decrease cost. It is a furtherobject and benefit of the invention to provide such a system which isadaptable to various other types of throwable, throw-and-catchable, orprojectable spinning toys and devices. It is a further object andbenefit of the invention to provide such an adaptable system to suchvarious toys and devices where the toys and devices are alreadyfamiliar, especially to children, so that bubble-making can be an addedfeature to such commonly known toys and devices and used withoutrequiring training. It is another object and benefit of the invention toprovide a bubble-making system which allows adults to pre-load a supplyof bubble-making solution, then allows children to play, mess-free, withthe device for an extended period and produce much larger bubblequantities without the need for repeated reloadings and or rinsing offof excess solution. It is another object and benefit of the invention toprovide a bubble-making system which more efficiently creates bubbles tomaximize the number of bubbles available from a given quantity ofsolution. Additional objects and benefits of the invention should becomeobvious to readers of the following disclosure, which is not meant tolimit, but only meant to exemplify the invention.

BRIEF SUMMARY OF THE INVENTION

The present invention may be all or a portion of a new bubble makingsystem, a portion of or all of a toy or other device employing thesystem, or one or more of the steps of the method employed to make oruse the system, toy, or device. The system may include a pre-fillable,sealed, and unspillable reservoir of bubble solution, one or morearmatures for converting the solution into bubbles, and a conduit fordelivering the bubble solution to the armature, only as needed duringuse. The system may also include the forces naturally occurring duringnormal use of the toy or device, as an inherent part of the deliveryconduit. The system employs a high-viscosity adaptation of hydrostaticvalving to control the flow of and prevent the inadvertent leakage ofthe solution.

Through the novel use of a high-viscosity adaptation of the propertieswhich cause hydrostatic valving, the system provides a constant “asneeded” supply of a carefully and automatically metered quantity ofsolution to the armature. When employed in devices and toys to whichmotion is already being imparted, such as objects commonly thrown,swung, or spun, the system eliminates the need for providing additionalbubble-making force, and eliminates the need for creating a dedicatedadditional airflow to create bubbles. By employing the natural andfamiliar motions and resulting forces of the device in which it is used,the system eliminates the need for added power, motors, fans,electronics, and other extraneous power, propulsion, and regulationcomponents. By employing the novel adaptation of hydrostatic valving,inadvertent leakage of the solution is eliminated without the need formechanical or complicated valves or unreliable vacuum effects.

The invention may be practiced by or using, or may be embodied in a toythrowing disk configured for spinning about a rotational axis duringflight and for producing bubbles during the spinning flight. The diskmay have a circular top panel and a sealed reservoir disposedsymmetrically about the rotational axis and comprising a plurality ofoutlets. The reservoir may be configured to receive and contain a bubblesolution having a viscosity of 50 to 300 cP at 20° C. The disk may havethe plurality of grid pairs equally angularly-spaced around and atop thecircular top panel, radially-outboard of the reservoir, each of thepairs comprising two parallel panels forming a radially-disposed spacethere-between for receiving the bubble solution from the reservoir. Theparallel panels may each be configured with an array of apertures forcooperating with passing air during the spinning flight to convert thereceived bubble solution into bubbles. And the disk may have theplurality of conduits providing fluid communication from the outlet tothe space for providing the bubble solution to the arrays of apertures.The conduits may have an inside diameter of 1 MM to 2 MM and a length of8 MM to 12 MM. The conduit, due to its inside diameter and length, andthe bubble solution, due to its viscosity, may cooperate to retain thesolution within the reservoir and conduit absent a sufficientcircumferential force vector, and the sufficient circumferential forcevector may be realized only during the spinning flight so that thebubble solution is delivered to the aperture array only during thespinning flight and cannot flow from the reservoir and the conduitexcept during the spinning flight.

The radially-disposed spaces may be from 0.3 to 0.7 MM wide. Theapertures may have a diameter of 2.5 MM to 3.5 MM. The apertures may bechamfered outwardly. The apertures may be continually vertically andhorizontally spaced from 3.5 to 4.5 MM apart. The aperture arrays on thetwo parallel panels may be coaxially aligned on an axis that is normalto the panels. The parallel panels may be 1 to 1.5 MM thick.

The invention may also be practiced by or using, or may be embodied in atoy throwing disk having a base disk plate with a domed top panel havinga downwardly-hanging circular perimeter, a reservoir, a plurality ofconduits projecting radially outwardly from the reservoir, the pluralityof reservoir outlets comprising conduit inlets to provide fluidcommunication between the reservoir and the conduits; a reservoir coverfor covering and sealing the reservoir and the conduits and having afill opening there-through for providing bubble solution to thereservoir; a removable and replaceable cap for selectively sealing thefill opening; and the plurality of bubble distribution armatures, eachcomprising a pair of parallel aperture array panels forming aradially-disposed space there-between; the plurality ofradially-disposed spaces equally angularly-disposed around the domed toppanel. The armatures may further have inlets providing fluidcommunication between an associated one of the conduits and thearmature's radially-disposed space. The conduits may beserpentine-shaped channels integrally-molded in the base disk platecommunicating with the reservoir through the reservoir outlets. Theserpentine-shaped channels may be created by an easily replaceable moldinsert to ease modification and optimization of the effective length ofthe channel. The toy throwing disk may further include a decal/gasket tohide and seal a seam between the reservoir cover and base disk plate.The domed top panel may have integrally-molded features for locating andfastening the bubble distribution armatures thereto. The locating andfastening features may be positioning nests and snap-receivers.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Reference is now made to the exemplary flying toy disks shown in theDrawings, which include bubble-making systems in accordance with or foruse in practicing the invention.

Referring first to FIGS. 1 through 10, flying disk 100 is shown. Thedisk is intended to be used just like a common flying toy disk such as aWham-O brand “Frisbee®” (http//en.wikipedia.org/wiki/Flying.disc), butwith the added feature of bubble-making. In fact, the disk shown wasconstructed using a Wham-0 brand “Frisbee®”. Polymer housing 150includes a circular domed top panel 152 approximately 11 inches in outerdiameter, from which hangs a circular perimeter 154 for grasping. Thedisk is approximately 1.4 inches high form the bottom of the perimeterwall to the top of the domed top panel, excluding the later-describedcap and filling opening. The housing defines an axis of rotation 156about which the object will rotate when it is flung in a spinningfashion, well known to most children.

The flying disk includes reservoir 102, three armatures 104, and threedelivery conduits 106 for providing selective fluid communicationbetween the reservoir and the armatures. The reservoir 102 issymmetrically disposed on the underside of the circular top panel 152 atthe axis of rotation 156 and includes three outlets 116 directedradially outwardly toward the armatures, which are outboard of the axisof rotation from the reservoir so that, as later explained, centrifugalforces act to suck solution from the reservoir during spinning flight,through the delivery conduits, and feed it to the armatures where it isconverted to bubbles and dispersed along the flight path as the diskflies and spins through the air.

The reservoir includes an interior chamber 108 for receiving and storingbubble solution, a fill opening 112 sealed by a removable andreplaceable screw-on cap 114, and the three outlets 116 for making thesolution available to the armatures through the associated deliveryconduits. The outer wall of the reservoir is upward conically shapedwith the outlets disposed at the largest diameter at the top of the wallto employ centrifugal forces to cause all of the solution therein to beforced and directed towards the outlets and enable all solution to beused up. The solution is of the type having a viscosity between 50 and300 cP at 20° C.

Referring to FIGS. 3 through 5, each armature includes a pair of grids118 straddling the exit 120 of each delivery conduit 106. In thisexemplary embodiment, each pair of grids was formed by folding a sheetof preferably 1.25 MM thick (more specifically, from 1 to 1.5 MM)perforated material 122 into a pair of spaced-apart perforated gridpanels 118, having a preferably 0.5 MM wide space (more specifically 0.3to 0.7 MM) 123 there-between. The material used was available only withsquare holes, so FIGS. 3 and 4 show an array having those square holes.But the square holes were then reworked into the preferred circularholes of FIGS. 6, 7A, and 7B. The exit end 120 of the associateddelivery conduit is captured in the space 123 between the panels asshown in FIGS. 4 and 5, and the panels are stitched together.

Referring to FIG. 6 through 7B, the resulting grid pair 118 includes anarray of round apertures 124 which are configured to become filmed overby the solution delivered into the space between them and to be blowninto bubbles by air passing through them as the disk travels in itsspinning flight. The apertures are preferably 3 MM in diameter (morespecifically, from 2.5 to 3.5 MM) chamfered outwardly at 45 angulardegrees, and continually vertically and horizontally spaced preferably 4MM apart (more specifically, from 3.5 to 4.5 MM). The fold was made sothat the apertures on the two parallel panels are coaxially aligned onan axis that is normal to the panels.

Referring to FIGS. 8A and 8B, each delivery conduit 106 is a flexibleelastic tube 126 32 MM in length with an outside diameter of 4 MM and aninside diameter of 2 MM, with reducing couplings inserted into each end.The reducing couplings are intake coupling 1281 which will connect toone of outlets 116 of the reservoir and outlet coupling 1280 that willbe captured within the associated grid pair space. The intake couplingis preferably 10 MM long (more specifically, from 8 to 12 MM) and has anoutside diameter of 3.2 MM and an inside diameter of preferably 1.5 MM(more specifically, from 1 to 2 MM). It is this coupling which providesthe “hydrostatic valve” function explained elsewhere in this disclosure.The outlet coupling is 10 MM long and has an outside diameter of 3.2 MMand an inside diameter of 2-2.5 MM. This coupling simply enables rigidattachment of the exit end 120 of the conduit to the associatedarmature. The total length of the assembled delivery device from theentrance opening at the reservoir to the exit at the armature is 42 MM.This arrangement causes capillary adhesion to prevent the solution fromescaping to the armatures absent the circumferential force applied tothe solution during its spinning flight. The delivery conduit servesthis valve function with no moving components or seals through the useof capillary forces similar to hydrostatic-valving.

The positioning of the smaller diameter hydrostatic valve in the intakecoupling provides the additional benefit of easing cleaning. If debrisenters the reservoir, this arrangement better retains it in thereservoir and prevents it from entering the conduit. This allows for therinsing of the reservoir and removal of debris that would otherwisetravel down the conduit to the armature and clog it.

Referring to FIG. 10, the bubble-forming area 162 of the grid panels isshown. This is the area wherein the apertures are filmed over by thesolution and where adequate airflow passes through the apertures tocause formation of bubbles. Upper shelves 160U are disposed atop thearmatures and lower shelves 160L are disposed below the armatures andspaced above the circular panel. The shelves together serve the purposeof intercepting solution which may have not converted into bubbles inthe bubble-forming area, to deflect and send that solution outwardlywith the bubbles as a spray of harmless mist in the trailing path behindthe flying disk. That solution would otherwise be problematic in that itwould coat the top panel and graspable perimeter wall, leaving a stickymess. Instead, that solution impacts the upper and lower shelves and isthrown there-from during flight as droplets that contribute positivelyto the visual affect of the bubbles . . . leaving the graspableperimeter dry and mess-free. The shelves also serve the purpose ofdirecting air into the aperture array to maximize bubble production. Thelower shelf can be trough-shaped to retain unspent solution thatdrizzles downwardly from the aperture array. This bowed shape yields theadditional benefit that it directs bubbles upwardly away for the toppanel during flight to prevent mess. This also allows a sheet of air toflow beneath the shelf and carry away any excess bubble solution and allbubbles produced up into the airstream to prevent mess.

The viscosity of the bubble solution for use in this system is withinthe range of 50 to 300 cP at 20° C. The delivery conduit's smallestinside diameters, 1.5 MM within couplings 1281 and 1280, and the lengthsof those tubular holes, 10 MM, were carefully selected after exhaustiveexperimentation to function as the afore-described high-viscosityversion of a hydrostatic valve with this bubble solution by relying onthe adhesive capillary forces within the tube to hold the solution inthe tube and deny its escape from the tube absent the stated sufficientforce vector. It was found that the length of the tube must be at least5 times its inside diameter to provide a hydrostatic valve-type offunction. It was also found that gravitational forces can cause thesolution to flow undesirably through an opening of a larger diameter, soan inside diameter of or smaller than about 3 MM is found necessarysimply to avoid inadvertent gravitational leaking. An inside diameter ofor larger than about 0.5 MM is found necessary to ensure that thesolution will be forced through the tube during the typical forces ofordinary flying disk flight . . . the “expected forces” present whenbubble making is desired. Between the diameters of 1.5 and 3 MM, thebalance between inadvertent leaking and proper hydrostatic valving isdifficult to predict, as it depends on things like the force with whichthe disk is thrown, the ambient temperature, the posture of the diskduring flight, etc. These things, all being unreliable to predict,reduce the reliability of the valving operation, increase the likelihoodof leaking, and thereby prevent the marketability of a tube having aninside diameter in that range.

Another factor at play is the required intake of air to replace thesolution expelled from the reservoir. The expulsion of solutionnaturally creates a vacuum with the reservoir and the conduit. Air has aviscosity of only 0.018 cP at 20° C. and it is found that an insidediameter of around 1.5 MM provides sufficient passageway for the intakeof air into the chamber under even the slightest vacuum so that all ofthe volume of solution leaving the reservoir can be replaced by inhaledair as soon as the spinning ends.

And because the system is so efficient, the reservoir holds enoughsolution, approximately 100 CC, to generate many bubbles for a longtime, versus older bubble-makers, which would be quickly depleted andrequire the user to refill every few minutes, interrupting play andmaking a mess.

Attention is now directed to FIGS. 11 through 19 where a secondexemplary embodiment is presented in the form of flying disk 200. Whilethe first embodiment 100 had been constructed as a proof-of-conceptprototype and was accordingly restricted, disk 200 is designed with aneye towards mass-production, both to employ features that enablemass-production, and to take advantage of benefits provided by suchmass-production methods as injection molding.

The bubble distribution armatures 204 shown in FIGS. 11 and 12 aremolded to incorporate all of the functional elements for the assembledarmatures of the first embodiment, with the connection to the deliveryconduit incorporated directly therein. The shape of the armature isreduced to more closely mimic the previously-explained bubble productionarea which reduces unnecessary weight and reduces unnecessaryaerodynamic drag.

Referring to FIG. 13B, while the first embodiment was built upon anexisting flying disk (FIG. 13A), the basic disk shape and size,including the domed top panel and the depending perimeter wall, aredesigned in this second embodiment to reduce overall weight and increaseoutside diameter to thereby increase the velocity of the spinningarmatures and optimize bubble production.

Referring now to FIGS. 14 through 19, it can be appreciated that thecomponent count is greatly decreased for this mass-production design.The components are a base disk plate 201, a reservoir cover 203, adecal/gasket 205, a reservoir cap 214, and three distribution armatures204.

The base disk plate incorporates this embodiment's domed top panel 252,depending perimeter wall 254, reservoir 202, reservoir outlets 216(which also serve as the conduit inlets and hydrostatic valves), andconduits 206. The conduits are integrally molded serpentine channelscommunicating with the reservoir through the pinched-down reservoiroutlets. The serpentine shape is created by an easily replaceable moldinsert to provide flexibility in the effective length of the channel, tooptimally match the length to the conduit width.

The reservoir cover 203 seals the reservoir and includes fill opening212. Removable and replaceable threaded cap 214 fits to the fill openingand allows filling of the reservoir. It also provides cover for theconduits and includes nozzles 220 for receiving the distributionarmatures and connecting the conduits thereto.

The decal/gasket hides and seals the seam between the reservoir coverand base disk plate.

The armatures are connected to the nozzles of the reservoir cover andfixed into proper position by locating features atop the base diskplate. The locating features include positioning nests 215 andsnap-receivers 217.

It should be appreciated that while the above embodiments both includethree bubble distribution armatures, any balanced plurality of armatureswith the matching plurality of associated plumbing may beless-preferably used. The plurality of three was merely chosen becauseit provided adequate space between the armatures for grasping the disk,and because it resulted in a device that was reasonable weighted.

It should be understood that while the invention has been shown anddescribed with reference to the specific exemplary embodiments shown,various changes in form and detail may be made without departing fromthe spirit and scope of the invention, and that the invention shouldtherefore only be limited according to the following claims, includingall equivalent interpretation to which they are entitled.
